Abstract
The invention relates to novel reducing compositions for reducing the disulfide bonds of keratin, comprising a regenerable reducing agent, such as an iodide salt, ferrocyanide salt, bromide salt and antimony(III) tartrate salt, capable of reducing the disulfide bonds of keratin, in combination with a consumable reducing agent, such as a salt or ester of thioglycolic acid, or a sulfite, bisulfite, hydrosulfite, metabisulfite or sulfoxylate salt, in which the consumable reducing agent is capable of regenerating the regenerable reducing agent by reducing the oxidized form of the regenerable reducing agent. Neutralizing compositions compatible with such reducing compositions, as well as methods for permanently waving or straightening hair or fur, are also encompassed by the invention.
